Input
Figure 5. Block diagram of 2 GHz production test board used for Noise Figure, Associated Gain, P1dB, and OIP3 measurements. This circuit
represents a trade-off between an optimal noise match and a realizable match based on production test requirements. Circuit losses have been
de-embedded from actual measurements.
